Abstract The development of innovative electrocatalysts for seawater splitting shows great potential large‐scale green energy. Specifically, interface engineering plays a vital role in improving surface properties and charge transfer. However, electrolysis encounters considerable challenges like chloride‐induced corrosion, impurities, microorganisms that hinder efficiency. Herein, we design highly durable electrocatalyst based on selenium‐enriched NiMn‐S x supported low‐density polyethylene‐derived spherical carbon‐Ni foam (Se‐NiMnS @SC/NF) using combination pyrolysis hydrothermal processes. resulting Se‐NiMnS @SC/NF bifunctional catalyst with hollow cycas cone structure exhibited exceptional electrochemical performance corrosion resistance alkaline an ultralow overpotential 146 262 mV the hydrogen evolution reaction (HER) oxygen (OER) to achieve large current density 500 mA cm⁻ 2 . In simulated setup, maintained cell voltage 2.07 V at , demonstrating outstanding durability over 100 h ≈100% Faradaic Se S doping heterostructured refines electronic boosts kinetics, while increases exposure active sites. Additionally, carbon layer provided strong making excellent electrolysis.
